According to man page accept(2), accept returns new client sockfd and
remote peer ip:port. This patch corrects the Accept() prototype in the
netdever interface to not take in an ip:port arg, but rather return an
ip:port for remote peer.
Tested with examples/net/tcpecho on wioterminal and nano-rp2040. Here's
a run with wioterminal:

This moves the netdev/netlink namespace out of drivers and into their
own packages. Also, defines netdev and netlink as L3/L4 and L2 OSI
layers, respectively. Move some L3 functionality from netlink to
netdev (GetIPAddr).
For netlink, add ConnectParams for NetConnect to pass in L2 connection
parameters (ssid, pass, auth_type, etc). Also adds connection mode
(STA, AP, etc).
For netlink, add SendEth and RecvEthFunc funcs to handle L2 send/recv of
Ethernet pkts.
